FRANK G. FEELEY, OF GHIGAGO,.ILLI1\TOIS, ASSIGNOR TO M. D. KNOWLTON COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

Application filed July 5, 1913. Serial No. 777,530.

To all whom it may concern Be it known that I, FRANK Gr. FEELEY, a Citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented, certain new. and use.

ful Improvements in Looking Devices, of which the following is a specification.

My invention relates to locking devices of the type disclosed in Letters Patent No. 97 4%,156, issued Nov. '1, 1910, and which are particularly adapted for use in adjustably securing the rotary cutting-and creasing devices used in paper-board working machinery, on their supporting mandrels.

As disclosed in the aforesaid patent, the collar or hub member which carries the r0- tary cutting or creasing device is provided with a bore tangential to the mandrel opening and intersecting the same to provide a communicating opening; and in said bore is located a locking device comprising a com pression bolt and three sleeves thereon having adjacent co-acting faces inclined in a direction whereby the central sleeve, under endwise compression by the adjacent sleeves, will be moved transversely of the bolt to a position in clamping engagement with the mandrel and so efiect the lockingof the cutting or creasing collar to said mandrel. In order that the central clamping sleeve may effect a secure clamping engagement with the mandrel, its under side is curved in a direction transversely of the mandrel to conform to and closely fit upon an extended surface of said mandrel.

To operate this locking device, that is, to effect the tightening or loosening of the ceni tral clamping sleeve in its relation to the mandrel, the operator turns the compression bolt in the proper direction by means of a wrench or similar tool applied to the end of the bolt. In doing this, experience has shown that there is a decided tendency'on 7 whereby it will be caused to bear at one point only on the mandrel when forced into clamping engagement'therewith. Thls obviously results in an insecure clamping engagement 'i with the mandrel and at the sametime has a Specification of Letters Patent.

tendency to mar and roughen the mandrel surface. 1 To avoid this has been the object of my present invention, to which end the invention consists in loosely connecting the mandrel clamping sleeve ofthe locking device with the collar or hub member of the cutting or creasing device in which it is carried in a manner whereby it will be held centrally of the mandrel while being free for lateral or transverse movement to and from its clamping position.

Referring now to the accompanying drawings forming part of this specification,*

Figure'l is a transverse section through a mandrel having a cutter secured thereto by means of alocking device embodying my invention, the locking device and the collar or device being in section to more clearly show the construction and operation of the parts. Fig. 2 is an elevation of the parts shown in Fig. 1, looking from the right-hand side thereof; Figs. 3 and 4 are views correspond ing to Figs'l and 2, respectively, and illustrating a modified form-of the invention. Figs. 5 and 6 are similar views illustrating another modified form of the invention.

. lhe collar or hub member 1 which carries opening. In this bore 3 is located thelocking device which comprises the compression bolt 6 and the three sleeves 7, 8 and 9,

mounted thereon, the central one of which, indicated at 8, being formed'with an opening or bore of greater diameter than that of the bolt whereby it maybe moved laterally of the bolt through the communicating opening between the bores to a position of clamping engagement with the mandrel, indicated at 10. To effect such lateral movement of the clamping sleeve 8, the adjacent ends of the three sleeves are inclined, as at 11, 11, in a direction whereby the central or clamping sleeve will be moved laterally of the bolt and to its said position of clamping engagement ing 15 therein.

with the mandrel under endwise pressure by the end sleeves. This endwise pressure may be exerted by any suitable means, the same as here shown being exerted by the bolt 6 which is threaded at one end into the end sleeve 9 and at its opposite end has a thrusthead 12 engaging the other end sleeve '7,

in the manner illustrated. A square stud or head 13 at the front end of the bolt permits of its engagement by a wrench or other operating tool.

In order to hold the central or clamping sleeve 8 against endwise movement in the bore 3 and centrally of the mandrel, in the manner and for the purpose hereinbefore referred to, any suitable means maybe employed. As shown in Figs. 1 and 2, it is so held by means of a screw is threaded into the collar 1 with its inner or lower end loosely engaging the sleeve within an open- This connection holds the sleeve against endwise movement while permitting of its necessary lateral movement on the bolt. In Figs. 3 and l is shown a similar holding means comprising a pin 16 in the collar loosely engaging the clamping sleeve within a slot or groove 17 therein. In Figs. 5 and 6 is shown another holding means comprising a spring 18 connected to the clamping sleeve and having a projection 19 at its upper side which engages the collar 1 within a seat or opening 20. These several difierent means for holding the clamping sleeve of the locking device centrally of the mandrel are merely illustrative of a few of the various means which may be employed for the performance of the described function and be within the scope of the invention and defined in the following claims.

What I claim is 1. In combination with a member provided with a bore having a lateral opening, of a locking device located in said bore comprising a plurality of parts having coacting inclined faces and one of which parts is movablelaterally of the bore under endwise compression by the other, compressing means co-acting with said locking parts, and means'loosely engaging the laterally movable locking part and holding it against endwise movement in the bore in which the 'locking device is contained during the actuother whereby the laterally movable part is held against endwise movement in the bore in which the locking device is'contained.

3. In combination with a mandrel and a collar thereon for carrying a cutting or creasing device, the said collar having a bore tangential to the mandrel opening andintersecting the same toprovide a communicating opening, of a locking device in said bore comprising a plurality of parts'having coacting inclined faces and one of which parts is movable laterally of the bore under endwise compression by another to a position in clamping engagement with the mandrel, compressing means co-acting with said locking parts, and means on the collar loosely engaging the laterally movable locking part s5 collar thereon for carrying a cutting or creasing device, the said collarhaving a bore tangential to the mandrel opening and intersectingthe same to provide a communicating opening, of alocking device in said bore comprising acompression bolt and a plurality of sleeves mounted thereon having coacting inclined faces, one of said sleeves having an opening of greater diameter than that of the bolt and being movable laterally of the bolt under endwise compression to a position in clamping engagement with the mandrel, and means on the collar loosely engaging the laterally movable locking part and holding it centrally of the mandrel and against endwise movement in the bore.
